Application filed May 17, 1917. Serial No. 169,268.

To all whom it may concern:

Be it known that LOHARLEs E. HASTY, a citizen of the United States, residing at Cleveland, in the county of .Guyahoga and State of Ohio, have invented a certain new.

and useful Improvement in Tube-Beading Devices, of which the following is. a full, clear, and exact, description.

This invention relates to a device "for beading or flanging over the ends of boiler tubes which have been-inserted through a flue plate. The object of the invention is to produce a device which will properly po-. sition an air gun or equivalent instrument so thatit may deliver :a properlydireoted.

blow to the end of the tube, and as the gun is moved around the, end of the tube,

maintain the" air gun'in its proper position. A further. object of the invention 18 to produce a device of the character which will obviate. the necessity ofthe operator twist.- ingxhis. arm in moving the. air gun into its succession of positions. in riveting.

Further objects. will appear as the descrip- Generally speaking, the 111-. vention may be. said to comprise the 'ele-.

forth 1 tion proceeds.

ments and combinations thereof set in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this. specification, in which Figure 1 IS. an elevation with portions in section of a device forming the subject matter of my invent on in position to operate; Fig. 2 1s a section uponthe line 2-'.-2 of Fig.1looking in the" direction of the arrow; Fig. 3 is an end elee vation of an expansible bushing; Fig. 1 is a sectional plan View showing a detail of construction. 1

Referring to the drawings. .1 indicates a' fine plate and 2.. a tube which extends;

through an opening in the flue plate, the

end of which tube is tobe beaded or flanged so as to be retainedby the flue plates 'W'ithin the tube 2 there .is an expansible bushing',' generally represented. at 3.. This expansible bushing consists of four parts which will be seen in Fig.3. The parts are. provided with grooves, such; as indicated at 4,.which grooves are in alinelnent" and within the grooves thereis a spr1ng-5=wh1ch normallyracts under compressionlto' pull the various elementsof the. expansible bushing towardeach other. 1 The expansible bushing has a central openinggenerally-"indicated at.

6, which is a tapered opening and is provided with screw threads.

Adjacent one end of the bushing the various parts thereof are provided with an extension such as indicated at 7 in Fig. 1. This extension is adapted to fit within a depressed portion which is formed in the tube 2 by the expansion of a shoulder 8.

This shoulder is previously formed in the tube, and forms an abutment which engages with the inner side of the flue plate so as to hold the tube against movement when the outer end of the tube is being beaded or flanged over.

The expansible bushing is supported upon a member 9 which at one end is conical in shape and screw threaded as indicated at 10, this conical screw threaded portion be ing adapted to cooperate with the segments of the expansible bushing for the purpose of expanding the same or permitting their retraction. The member 9 extends beyond the bushing and at its end has a squared portion ll'by which the member 9 maybe turned.

At the threaded end of the member 9 F there is a post 12 which extends through an openingin a plate 13 that bears against the ends of the sectional bushing. Upon the end of the rod there is a nut 14: and between the nut and plate there is a spring 15. The purpose of this arrangement is to prevent the sections of'the expansible bushing from moving with the threaded portion of the member 9 as it is turned.

Upon the member 9 and beyond the threaded portion there is a tubular member 16 which at its inner end is provided with l a plurality of pins 17 which pins engage in engages withia depending portion 21 of a sleeve 22. This sleeve is a split sleeve andis; adapteditoencircle. the casing 23 of an air gun or similar device. The parts of the; split 'casingare secured and held byineans':

. of boltsr2l which extend through lip pore tions of the sleeve 22.

The end of the rod 20 receives a nut 2% which bears against the portion 21 of the sleeve 22, and holds it in position upon the rod. Upon the casing 23 there are collars 25 which lie upon opposite sides of the sleeve 22, these collars hold packing such as indicated at 26, the packing lying against the sleeve and holding the sleeve against rattling or jarring as the air hammer is operated.

Supported upon the upper portion of the sleeve 18 is a guiding member 27. This guiding member is for" 1661 in two parts which parts are secured together by a wing nut 28. The member 27 has angular sides and receives an angular sided tool 29 which tool is operated by the air gun or similar mechanism within the casing 23. The tool 29 has a suitable head adapted to engage with the end of the tube to be beaded, and as the tool 29 is reciprocated, in a manner Well known, the end of the tube will be flanged over. The member 27 is pivoted upon the sleeve as indicated in the drawing, so that this member may assume an angular position with, respect to the sleeve 18 upon which it is mounted.

The rod 20 is formed with overlapping portions 20 These overlapping portions have an opening through them which is occupied by a bolt 27. The bolt is squared at one end as indicated at 28 This squared portion lies within asquared opening formed in one of the portions of the rod. The other portion of the bolt is rounded and receives upon the outer threaded end a wing nut 29 Surrounding the bolt is'a plate 30 provided with projections or depressions which are adapted to cooperate with similar projections or depressions formed upon the inner portion of the wing nut.

The two parts of the rod 20 may be adjusted at an angle with respect to each other by loosening the wing nut 29 which permits relative movement of the two parts of the rod 20. The tightening of the wing nut will hold the two portions in their adjusted angular position.

This construction is made use of, to vary within limits the angular relationship of the tool 20 to the work.

In operating the device the hand of the operator may grasp the handle of the air gun, and without twisting the arm of the operator the air gun may be moved in a circular path so that the tool 29 is in succession.

presented to different portions ofthe end of the tube. The swivel mounting of the sleeve 18 and'the sleeve 22 permit of this movement. I 1 l,

Because the arm of the operator does not need to be twisted it is possible for the-open ator to effect a much better job of beading than would be possible under other circumstances.

Having described my invention, I claim 1. In a tube beading device, a supporting member adapted to be mounted in a tube to be beaded, a hammer casing, a supporting means for the hammer casing said supporting means being free to turn upon the supporting member, the hammer casing being said supporting means having an axially swivel connection with the supporting mem her and with the said hammer casing.

V

Ina tube beading device, a supporting member adapted to bemountedin atube to be beaded,- a sleeve supported upon said member and free to'turn thereon, ahammer casing, a sleeve supported upon said hammer casing and free to turn thereon, means engaging opposite ends of said sleeve upon the hammer casing, packing between the said member and the sleeve, and a rod at its opposite ends secured to the said sleeves.

8. In a tube beading device, a rod having a tapered threaded portion, an expansible bushing adapted to cooperate with said threaded end portion, a tubular member upon the rod said tubular member being provided with pins adapted to engage in slots formed on the end of the expansible bushing, a sleeve member mounted upon the tubular member and free to turn thereon; means carried by the rod for holding the sleeve member on the tubular member, and

means associated with the sleeve member for supporting a hammering device.
